3. Change the play direction by reversing
the direction that you are turning the
pan knob.
4. During play, u
p to a point, the more you
turn the ring, the faster the waveform
accelerates. If you turn the ring as
far as it can g
o, the play speed does
not change, but the zoom box quickly
moves in that direction. Use this
maximum rot
ation feature to replay a
portion of the waveform that you just
saw and want to see again.
5. Pause the play-pause feature by
pushing th
e play-pause button again.
Searching and Marking Waveforms
You can mark locations of interest in the acquired waveform. These marks help you limit your analysis to particular regions of
the waveform. You can mark areas of the waveform automatically, if they meet some special criteria, or you can manually
mark each item of interest. You can use arrow keys to jump from mark to mark (area of interest to area of interest). You can
automatically search and mark many of the same parameters that you can trigger on.
Search marks provide a way to mark a waveform region for reference. You can set marks automatically with search
criteria. You can search for and mark regions with particular edges , pulse widths, runts, logic states, rise/fall times, setup
and hold, and bus search types.
To manually set and clear (delete) marks:
1. Move (the zoom box) to the area on the
waveform where you want to set (or
clear) a search mark by turning the pan
(outer) knob.
Push the next ( ) or previous ()
arrowbuttontojumptoanexistingmark.
2. Push Set/Clear.
If no search mark is at the screen center,
the oscilloscope will add one.
